CA 2469410

A metallic separator in which falling off of the conductive inclusions projecting from a matrix surface is prevented, whereby the contact resistance is decreased, resulting in increasing the characteristics for generation of electrical energy. A metallic separator for a fuel cell comprises conductive inclusions in a metal structure, and the conductive inclusions project from a surface of a matrix to a height of 1 to 3 micrometers.

L'invention concerne un séparateur de métaux destiné à une pile à combustible dans laquelle une inclusion conductrice est contenue dans la structure métallique et disposée en saillie à partir de la surface de la matrice par 1-3 mu m. L'inclusion conductrice disposée en saillie à partir de la surface de la matrice est protégée contre le détachement, et il en résulte que la résistance de contact est réduite, améliorant ainsi sa performance de génération.
